PIPE-REPAIR DEVICE.

To all wim/it fit may concern.'

lle it known that l, LINCOLN VAN GIL-Drin, a citizen ot the United States, residing,` in `iJentnor, New Jersey, have invented certain ln'iprovenients in Pipe-Repair Devices, ot which the following is a specitication.

@ne object of my invention is to provide a. device or combination of parts, particularly adapted iter the repair ot large size conduits such as wooden, steel or iron pipes; it being` especially desired that the device shall be of such construction that may be easily and conveniently transport ed, that it shall be capable of being` quickly and conveniently applied to a pipe or conduit to stop a leak therein, that it shall be relatively inexpensive, and linally that it shall be capable ot application to a leaky conduit without requiring that said conduit be put ont of service or the liquid be drawn ott from the same.

l-ttnotlier object of my invention is to provide a pipe repair device which shall not only bc relatively inexpensive to make and apply, but which shall consist otl parts comparatively easy to make or obtain.

rl`hese objects and other advantageous ends I secure as hereinafter set forth; reference being` had to the accompanying` drawings, in which Figure l, is a side elevation of a conduit illustrating my invention as applied thereto tor the purpose of stopping' a leak or a break, the view illustrating1 the repair device as partly in section; Fig. 2, is a trans verse section of the conduit, illustrating' my invention in end elevation; and Fig. 3, is a side elevation of a conduit illustrating,` a

forni of the invention in which relatively short tie bolts may be employed.

ln the above dra-wings, X represents a section of the riveted steel pipe or conduit which is illustrated as having` its lengths connected by flanged collars X riveted together in the well known manner.

ln the event ot' a leak occurringin such a conduit l apply to it my repair device which consists essentially of two bells 1 and 2 made in any number of separable sections connected together by bolts 3 and mounted fcn the pipe or conduit X at a distance from each other depending upon the length of the conduit which is leaking. For the purpose of making liquid-proof joints between the conduit and each bell, I place packing between said parts consisting in the Specification of Letters Patent.

serial No. 657,661.

present case, of a body of jute 4 and a mass ot lead 5, which is applied in the manner well understood in this art and afterward ,alked. Each of the bells ismade with an interior annular rib 6 so placed as to torni an annular recess whose wall nearest the conduit is inclined as indicated at 7 it beingv noted that the edge or mouth of the bell extends some distance beyond said rib.

Extending between the bells and into the recesses formed by their ribs 6 and their mouth portions S, is a. body of staves 9 of suitable length and material, whose ends rest upon the inclined portions 7 ot the ribs 6 and which are held in the form of a cylindrical conduit by adjustable hoops or bands 10, as shown. It will be noted that the ribs 6 are so placed as to support the staves 9 at such a distance from the conduit as will permit them to pass over the flanges ot the collars X without touching them.

The two bells are connected to each other by any desired number of longitudinally' extending,` tie rods 11, which engage suitable lugs formed in the present instance on the ieripheries of their mouth portions 8, although itis obvious that said bolts may be connected to the bells in any suitable inanner without departing from my invention. ln applying' my repair device to a length ot pipe, the bells are clamped thereto by the bolts 8, at such distances from each other as will include between them that portion of the pipe having` the leak or break which itis desired to stop. Said bells are packed to the pipe or conduit by the use of jute and lead, as shown, after the staves have been loosely mounted in the position shown so as to extend between the bells and rest upon the annular ribs G. rlhe bands 10 are then loosely applied around the staves and the tie rods 11 are made to connect the two bells in order to prevent their movement upon the conduit away from each other. The adjusting turn buckles or nuts 12, on the stave bands 10, are then tightened so as to draw said staves into a. tight cylindrical container and it is obvio-us that for this purpose their end portions compress suliiciently to permit of the complete closure of the spaces between them. By means of suitable packing', such as jute, introduced between the ends of the-staves and the mouth portions 8 of the bells, as indicated at 13, practically all of the leakage or" liquid is stopped and, inally, melted lead, or other suitable packing 14, is placed between the staves and the outer portion of the mouth S. By this means it is possible to repair a conduit of practically any size, even while it is in service carrying` liquid under high pressure and I have found that under these conditions it is possible'to successfully apply and call; the various packing's as shown, using' melted lead in the customary manner. Y

r"ne invention is particularly applicable to cast iron pipes which frequently develop longitudinally extending cracks and if the distance between the two bells be such that the tie rods ll become abnormally long, I may, as shown in F 3, apply to the staves a sectional clamping` ring or collar l5, thereafter extending' relatively short tie rods ll"L between it and the bell to which it is adjacent.

If it should be found necessary to stop a leak occurring,` just beyond and outside one of the bells, that form of bell shown at 2 may be employed. This latter is of a double mouthed form z'. c. it is formed to receive staves 9 in either face, so that the repair device may be continued indeiinitely by the use of bells of this form, or, if but a small andV localized leak occurs, a single bell l, with a set of relatively short staves, may be used with the device previously applied, as shown.

l claim:

l. A pipe repair device consisting of two sectional bell-mouthed members mounted on a conduit and thereoi'; means forforming a Huid tight joint between each of said members and the conduit; a tubular structure surrounding the conduit but spaced away from the same in structurally independent position for its ends to respectively enter the two bell-mouthed members; and means for holding' said members together.

A pipe repair device consisting' of two bell-mouthed members, each having an iniuid tight joint between each of said members and the conduit; a tubular structure of a diameter to enter the bell-mouthed memlbers and rest upon said rib; and means for holding the bell-mouthed members together. j 3. A pipe repair device consisting` of two members capable of being' mounted on a conlduit and each providing an annular recess;

ieans for forming' a fluid tight joint between each of said members and the conduit; series of staves arranged in tubular form laround the conduit; the ends of said staves entering the annular recesses of said members; annular structures surrounding' the staves for holding' them together; and tie rods connecting the bell-mouthed members. I 4l. A. pipe repair device consisting ott a plurality of bell-mouthed structures mountled on a conduit; a tubular structure extending` around the conduit and fitting each of said bell-mouthed structures; a collar lmounted on the tubular structure; and tie bolts between said collar and one of the bellmouthed structures for preventing' its movement upon the conduit. ln testimony whereof, I have signed my 'name to this specification, in the presence of two subscribing witnesses.
